4 Schematic of the Pumping Principle 1. When the helical twisted rotors are rotated a vacuum is created, which draws liquid smoothly and without interruption into the pumping chamber. 2. By further rotation the liquid is locked in between the rotors and the rotor housing. 3. Liquid is transported to discharge side. 4. Liquid is discharged, smoothly and with the lowest pulsation worldwide. When changing the direction of rotation the flow is reversed Main Features 9 pump sizes Pressure up to 9 bar/128 psi (higher pressure on request) Vol. delivery up to 180 m³/h Installation Horizontal (standard) Vertical (on request) Materials in contact with the medium Ni-resist Stainless steel O-rings NBR Viton (other materials on request) Surface finishing Painted Pipe connections Flanges Milkpipe threads Sterile threads Accessories Quench-tank Heating/cooling plate Basic frame Height adjustable frame Portable frame Current reverser Frequency exchanger Drive Gear motor Variable speed gear motor Standard clutch Safety clutch

5 Shaft Sealing Mechanical Seal with Quench For the sugar industry special mechanical seals were developed which are strain free, independent of direction of rotation and spring suspended on the atmosphere side of the seal (dry). In the standard version the O-rings are made of Viton and the mechanical seal surfaces are made of tungsten carbide. The mechanical seals are lubricated and cooled by a nonpressurized quench system. The secondary seal is also a mechanical seal. Single Mechanical Seal This mechanical seal is strain free, independent of direction of rotation and has enclosed springs. In the standard version the O-rings are made of Viton and the mechanical seal surfaces are made of silicone carbide. A non-pressurized quench system can be supplied as an optional accessory.
